### sdbmHashAlgorithm
|
||||
|
||||
This algorithm is a simple hash-algorithm that hashes it input string `s` into a whole number.
|
||||
|
||||
Use `split('')` and `Array.reduce()` to create a hash of the input string, utilizing bit shifting.
|
||||
|
||||
``` js
|
||||
const sdbm = str => {
|
||||
let arr = str.split('');
|
||||
return arr.reduce((hashCode, currentVal) =>
|
||||
hashCode = currentVal.charCodeAt(0) + (hashCode << 6) + (hashCode << 16) - hashCode
|
||||
,0)
|
||||
}

||||
// console.log(sdbm("name")) // -3521204949
